As previously stated bulk allows you to OH even after being critically damaged.

Your gunners...only thing i can say there is AA get experts and convert them to vets,
unless your willing to pay for boosts, vets, experts, and etc.... AA and get more experts.
The main thing with your gunners is there gonna have a bad at level spread all the way up
until about iowa level. But you'll notice with every level over you'll continue to get a
tighter and tighter spread but hardly ever a perfect blockshot, so all we can say on this
point is keeping plugging away at it and don't give up.

"for your gunners:
thats normal... at level guns spread sucks whether your using LHE,HHE,AP still the same
unless you boost your gunner a bit it will be little better but not as tight as hiigh
level gunners does, that is why we should need to level our gunners 10 lvl ahead of our bo ^^"

10 levels ahead is at level 40 is not even close to where they realistically need to be.
10 levels ahead at level 40 will translate to virtually nothing by 89 where it is
essential to maintain at the minimum 2 levels above.

@Adamai:

Happymeal stated it correctly. Bulk Head increases the amount of DP you can lose
before you lose the ability to overheat. You are able to check this in port on your
ship's hull. The red line on the DP bar is the margin at which you can no longer
overheat. Try adding 100 bulk to a BB5 and notice how far it decreases. It's not
super effective, but it doesn't hurt to run any.

bulq head armour is a genral overall strenthening of the ship. i dont think any one really
knows how it works, all you will get on here is lots of peoples versions of what they
think it is. i havnt managed to find anything on it.

@dersico yes, its kinda true cause light shell do less damage but you gain range big time
than heavy ones, but i see in blitz atm its really hard to use LHE due to the fact that
their small room/space to use ca's range more effectively but its really fun to see your
enemy being pounded at your farthest range with LHE without you getting to his range...
and this practice for ca players going to bb

thank you guys. you've been very helpful

If I remember right, CA shells lose 200 damage when switching from HEH to HEL ammunition

bulk head will reduce the amount of health you need on your ship to still be able to
OH. Baically, it allows you to take more damage before losing the ability to overheat.

The only ships that are going to be stopping any shells on the US line that are worth
trying it on are the New orleans, portland and northampton. You might oull it off in
the balti. And it takes at least 8" i think for a 6" shell.

Your spread wont get good unless theyre ebve, or theyre very high level. Its
because of the ability.

The ammo makes a huge difference. In your CA, that heavy shell causes more
damage than a normal or light, but less range. Normal is the medium damage and
range, while light has the most range (matching armor peircing, i beleive) and the
least damage. It still does alot. Just not as much as heavy.

armor:
all i know with bulk is that even youve been hit critically during OH it wouldn't affect
your OH, i use 2" i dont know if other use bulkhead

well i don't armor a lot maybe 5"-8" belt

but .2-.4 belt and bulge until you loose 1 knt (decrease bulge by 1 if knt decrease)

for your gunners:
thats normal... at level guns spread sucks whether your using LHE,HHE,AP still the same
unless you boost your gunner a bit it will be little better but not as tight as hiigh
level gunners does, that is why we should need to level our gunners 10 lvl ahead of our bo ^^

but guns lower than 30 get a good spraed
